PERCUSSIVE TOOL.

To all. who'mit may concern: U

Be it known that I, LEWIS C. BAY ns, a citizen of the United States, andresident ,ofEaston, in the county of Northampton ""let chambers 3 and 5,is located a vertical from which cylin-- the parts as will hereina Isive Tools, 'fication'.

- mission and exhaust 'eindState of Pennsylvania, have invented -'a newand useful Improvement in Percusof' which the following is a speci--Thisin ention has for its object to provide'j certain improvements inpercussive tools, and particularly in valve mechanism therefor.

. My invention relates to that type of valve mechanism in which a.winged oscillating valve is" employed for controlling the adwhichoperates the work piston of the tool, a novel mounting being providedfor the valve whereby its operation is facilitated and its lifeprolonged.

. In the accompanying drawings, Figure is-a longitud nal SCCtIOIIthrough the yalvc:

chest and seat, a portion of the valve being broken away to more;clearly illustrate the spindle on which it is mounted. Fig. 2 is aninverted plan view of the valve and chest, Fig. 3 is-a detail,transverse section taken in the plane of the line A of Fig '1. Fig.4 isa view in side elevation of tlie spindle, Fig. 5 is a plan view andFig-'16 is a detail view showing more clearly the-construction of theinner end of the body portion of the winged valve.

The valve chestis denoted by 1, which chest is provided with a motivefluid inlet 2 leading:to an inlet chamber -3 and a motive fluid outlet 4leading from an outlet chamber 5. Intermediatethe inlet andoutcylindrical chamber 6, drical chamber slots 7 and 8 lead to the inletand outlet chambers 3 and 5 respectively;- These slots 7 and 8 and theintermediate cylindrical chamber 6, all open through the inner face ofthe valve chest 1, for permitting the ready assembling and removal ofter appear.

A double winged oscillating valve. is located in the valve chest, thecylindrical body portion- 9 ofwhich valve cylindrical chamber 6 .in thevalve chest. The wing 10 of the valve is located within the slot 7', andthe wing 11 of the valve is with respect to each other,

located within the slot 8. The slots 7 and 8 and the wings 10 and 11,are so shaped that the: valve is for alternately opening and closingcommunication between the inlet'chaiii opening and closing'communicationbetween the outlet outlet chamber 5.

The outer end of this spindle 16 isextended into a recess 17 at the outer end of the chamber 6, and theinnerend of the trunnion 16 may be provided with an enlarged cylindricalbase 18 fitted to the in: ner end of the chamber 6. This spindle islocked againstrotative movement by a pin 19 inserted into a recessformed. partly in the walls of the base 18 of the spindleand her 6, thebody portion 9 valve being-flattened as shown at 9 for oscillate on thespindle 16.

The valvefandspindle may be removed from and inserted into't'he chestlthl'ough inncrface the chest (lithe p may be readily inserted. into and removed whenthe chest is removed from its seat.

What I claim is:

4:. A valve mechanism including a'walve chest having a cylindricalchamber opening through itsinner face, a winged valve havingits bodportion fitted to said chamber and a spin le on which the valveoscillates provided with an enlarged head fitted to the inner end ofsaid chamber, said spindle being removable through said inner faceof'the valve chest. g

5. A valve mechanism including a valve chest having acylindrical'chamber opening through its inner face, a winged valvehaving its body portion fitted to said chamber and a spindle on whichthe valve oscillates provided with an enlargedhead fitted to the innerend of said chamber, said spindle and valve being removable through saidinner face of the valve chest.

6. A valve mechanism including a valve chest having acylindrical-chamber opening through its inner face and a concentricrecess at the outer end of the chamber, a winged valve having itsbodyportion fitted to said chamber, and a spindle on which the valveos'cillates,'having.its inner end provided with an enlarged head fittedto the inner end of said chamber and its outer end extended into saidrecess' v 7.
